ATTACHMENT FOR WATER-SUPPLY PIPES.

To all whom it may concern:

Be it known that I, RUDOLF F. SCHOTT, a subject of the Emperor of Germany,residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Attachments for Water-Supply Pipes, of which the following is a specification.

The hereinafter described invention relates to a water saving or economizing attachment for use in connection with the discharge nozzles of water supply pipes for use in hotels, restaurants and households, the object thereof being to economize the water consumption in accordance as to the water quantity desired for use at different periods or times of the day. For instance, in connection with the pantry or kitchen supply nozzles when water is drawn for the washing of certain dishes, a spray stream is preferable tothe heavy solid stream usually permitted to flow from said nozzle and where a spray stream is utilized there is less consumption of water than where a solid stream is permitted to discharge. The present invention, therefore, contemplates the form of an attachment whereby the water user may at will permit the outflow of a spray stream delivery from the discharge nozzle or a solid stream therefrom, dependent upon the will of the user of the water. By this means the water consumption may be properly proportioned to the use to which the waten is to be placed, thereby creating a material saving in the excess-water which at present is permitted to run waste, which isa very important and essential factor to be taken into consideration where water is charged for by meter readings and in such territory where the water supply is of limwherein a somewhat heavy charge is made per thousand feet of water consumption.

The hereinafter described invention is one which will appeal to the householder and equally so to the managers of hotels, restaurants and cafes, etc., -or such. establishments wherein a large monthly consumption of water is made, permitting, as it does, a material saving in water to be made and consequently a material saving in the monthly water bill.

'To comprehend the invention, reference should bemade to the accompanylng draw vings, wherein,

Figure l is a sectional elevation illustratmg the invention as applied to the nozzle of an ordinary valve controlling water supply nozzle, illustrating the controlling valve of the attachment in position for directing the dlscharge of water into a sprinkler head or rose carried by the attachment.

Fig. 2 is a broken detailed view similar to Fig. 1 illustrating the controlling valve of the attachment turned to close the flow of water into the sprinkler head or rose, and to direct the same as a solid stream through the outlet stem thereof.

Fig. 3 is a sectional plan view taken on the line 3+3 of Fig. 1 of the drawings and viewed in the direction of the arrows.

Fig. 4 is a view similar to Fig. 8 taken on 2 is divided by means of the central partition piece or diaphragm 4c, and within the barrel above the partition l is seated a 1'0- tatable plug valve 5. The said rotatable valve 5 is provided in the bottom wall thereof with a plurality of vertically disposed outlet ports 8. The lateral ports 6 in the rotatable valve 5 are adapted to be moved into registry with the lateral ports 9 formed in the vertical wall of the barrel 2, while the vertical ports 8 are adapted to be moved into registry with the vertical discharge ports 10, formed in the central partition piece or diaphragm & of the barrel 2. Within the plug valve 5 is fitted a basket strainer 11. which is designed for the purpose of preventing foreign substances passing through the ports 6 of the said valve 5 and the ports 9 of the barrel 2 when the ports are in registry.

In the present case, the barrel 2 is illustrated as having formed integral therewith a sprinkler head or rose 12, into which the I water discharging through the lateral ports 6 and 9 respectively finds its outlet through the perforated bottom 13 thereof, and which discharges therefrom in a spray-like form, or the water stream discharging from the strainer head or rose 12 is broken up into a head or 'rose by means of the spriligheld handle 14', thestem" 14" of which works through a slotted section15' of the depend: ing rim 15' ofthe sprinkler header rose 12', the inner end'of said stem 14' being corinected by post" 16 to the bottom ofjthe valve 5, said post extending" through'an apert'ur'e' in f the central diaphragm" or bridge '41 of the barrel 2. Eaeh'endf of the post 16 terminates 111a squareshankt'o fit" Within asquare opening infthe bottom of the valve 5 anda' corresponding opeiiing'iii the'inner end of the stem 14" of the handle 14, being held in place by the'heads' a:

There is interposed between the inner end of thes'tein' of the" handle 14 and the partition 'iv'all or 'diaphragin'zl' of the barrel 5 a helical spring 17, the upper end of the said spr'ingb'eing'attached to the Wall of the said barrel 5 and the lower end to'the stem 14 of the handle 14;, the said springeXer'ting" adownjivard pressure on the stem 14 and post16, the pressure thus exertedholding the ya'l've5 seated on the upper'face' of the partition'or diaphragm 4 of the valve 5.

It will be' understood thatthe Water flow through the nozzle 1 is controlled by the ordii iary hand actuated valve 18.

The-valve 5' is thrown or rotated t'o plac'ef thejports" 6 andthfe ports 8 into registry respectively With the ports 9 and 10' of the barrel 2by' means ofthebtafore nhe'nti'o'hed handlelt, which as swung in oned'irection' pla ces'theport's' 8 of the valve'5 int'o r'egis trywith the ports 10 ofthe b rrel ea and'oh' therel'eaise ofpre'ssure from the said handle thetorsional"strain of the helical spring? 17 returns the" handle 14 to normal position and plac'esthe ports 6 of the valve 5 into registry with the ports 9101 the barrel 2,

which is the normal" position of the said valve 5.

VVhe'n 'in' norrnal position" to ohtain a spray of Water, presuming of course, that the valve 18-,isthrown to open the ater flow through the nozzle 1, th'e spring" held handle 145 lies, asin' 3 tof'posit'ionthe valve 5 so that the lateral ports'6 thereof are in registry with the lateral discharge ports 9 bf the barrel 2, at Which time the water will be fromflthe nozzle through theports 6 and 9 to the interiorv of therose '12, from which it escapes'throug'h the per forations in the bottom Wall 13, the escape beinginthe form of small j etsor sprays. l

hen aheayyor solid stream of Water is desired the haiidle 14 is moved against the tensionof sprin'gxl'f' tioipla-ce the outlet ports 8 of the rotatable valve 5 into registry with the vertical ports 10 of the bridge or part1 tion piece 4: of the barrel 3, which permits of a'direet'ucwiiward flow of the Water into the tubular extensionor stem 3 of the said barrel 2 and fro1n'Wliich"it discharges 'asa solid}streain, I V g 7 Vi he intentiorfisapplicable for use" ndZ'zl of"house'supply water pipes; it is more particularly designed for use in colineet'ioii' with th'e"l'1otwater discharge noz zle, so that a spraystreanifof hbtjwaper may at certain times be brought" into play, whileatfother" times asolid stream of hot water maybe the attachment.

When the water is seeing as a"*solid" in ctlnn ectioh" with either" of the discharge permitted to issue through strealn' through the attachmentand away therefrom, the s'treaiiibf flowing Water Will was-11 1i cleanse the wall of the basket screeh' 11 f matter or foreign substance which may adl eret'o or have aecmaalzita en the inner wall 15 surface thereof; thus maintaining" the same clean of such fo1eigir substanc'e'lf its preferred enibodiment and is attached to plied tlieretb in any Well known manner,-
